Building with VINNAPAS®Oct 06, 2016 | 6:42 min

Sand, cement and water: for a long time, that was all that a mortar needed. But expectations are rising. As a result, polymeric binders are now added to the dry-mix mortar blends used in many applications.These binders include VINNAPAS®, a dispersible polymer powder from WACKER. VINNAPAS® makes mortar more pliable yet stronger, so that construction workers do not have to use as much of it – a welcome development, especially in places where construction is booming. Like India.

Aluminum composite panels can increasingly be found on building exteriors. In order to keep the thermoplastics used here from compromising the fire safety, manufacturers incorporate fire-retardant fillers.Developed by WACKER, GENIOPLAST® Pellet S is a silicone additive that is suitable for a diverse range of thermoplastic polymer blends. It makes such flame-resistant blends easier to manufacture, even when added at a concentration of only one percent.

Wood is one of the oldest building materials known to humans – and remains very popular to this day. A coating is used to provide wood with long-term protection against weathering. With SILRES® WH, WACKER has developed a wood preservative which is perfectly suited to this role. SILRES® WH is a silicone resin which covers the surface of the wood with a flexible, elastic film. This means that no moisture can penetrate the wood, even after years of exposure to sunlight and rain.

Bonding has several advantages over clamping, riveting, and screwing. Whether in a car or on a patio: bonds need to be flexible, but at the same time resistant to tearing or shearing. GENIOSIL® XT - a new product range which does not require organotin catalysts or the addition of solvents - helps to meet these requirements.

Gypsum construction elements and materials have many advantages: they are environmentally friendly to manufacture and can be rapidly and inexpensively processed. But, when used in damp locations, gypsum must be made water repellent. In SILRES® BS Powder S, WACKER now has an active substance which achieves this water repellency more efficiently and reliably than those previously used.

In theory, a fire could break out in any type of building. For buildings with a steel frame, a specialty coating is now available which can save lives in case of a fire. The protective layer’s sophisticated composition includes a binder from WACKER.
